One of the things that turned up, during a long-overdue cleanup of my office, was an old yellowed copy of the New York Times dated July 24, 1992. One of the front-page headlines said: "White-Black Disparity in Income Narrowed in 80's, Census Shows."

The 1980s? Wasn't that the years of the Reagan administration, the "decade of greed," the era of "neglect" of the poor and minorities, if not "covert racism"?

More recently, during the administration of America's first black president, a 2011 report from the Pew Research Center has the headline, "Wealth Gaps Rise to Record Highs Between Whites, Blacks and Hispanics."

While the median net worth of whites was 10 times the median net worth of blacks in 1988, the last year of the Reagan administration, the ratio was 19 to one in 2009, the first year of the Obama administration. With Hispanics, the ratio was eight to one in 1988 and 15 to one in 2009.
